The first great discovery in chemistry was the discovery of oxygen. It started with a man named Joseph Priestly challenging the thought that they were only four elements. Those being fire, water, air, and earth. He claimed that air was not an element, but instead made up of multiple things. He conducted an experiment. Priestly heated an orange powder, which changed into mercury. A gas comes off of it. The gas is oxygen, but Priestly does not know that. So on a trip to Paris, he takes his experiment to Antoine Lavoisier. Lavoisier calls the gas oxygen. Together they publish their discovery, and oxygen is born. Lavoisier also publishes a whole list of elements like sulfur and hydrogen. This all starts thoughts on materials used in industry, like steel and plastics. All of that was jumpstarted by the discovery of oxygen.
The next great discovery was the discovery of atoms. Atoms were discovered by John Dalton in an effort to weigh the elements. Dalton published volumes on atomic weight. He concluded that when a solid is colder, its atoms travel slower, and give off less energy. When a solid is warmer, its atoms travel faster, and give off more energy. This atomic weight in protons was a great discovery. It led to the discovery of molecules. Amadeo Amagadro discovered the different types of molecules. Molecules, the combination of atoms, were a great discovery in chemistry.
